live555 交叉编译移植到海思开发板
本文章参考了。http://blog.csdn.net/lawishere/article/details/8182952,写了hi3518的配置说明。特此感谢
1、首先到它的主页下载一个源码包:
http://www.live555.com/liveMedia/public/
我下载的是latest的,具体什么版本还真不清楚
2、放到linux目录下解压:
- root@kubuntu:/home/frank tar zxvf live555-latest.tar.gz
- root@kubuntu:/home/frank# cd live
- root@kubuntu:/home/frank/live#
3、首先尝试在PC的Linux上编译:
区别于传统的源码包,不是传统的配置方式,而是通过genMakefiles配对目录下的config.*文件生成Makefile
- root@kubuntu:/home/frank/live# ./genMakefiles linux
- root@kubuntu:/home/frank/live# make
编译很顺利,然后上网找一个*.264文件放在当前目录下
执行mediaServer目录下的live555MediaServer服务器原型
- LIVE555 Media Server
- version 0.75 (LIVE555 Streaming Media library version 2012.11.08).
- Play streams from this server using the URL
- rtsp://192.168.1.41:8554/<filename>
- where <filename> is a file present in the current directory.
- Each file's type is inferred from its name suffix:
- ".264" => a H.264 Video Elementary Stream file
- ".aac" => an AAC Audio (ADTS format) file
- ".ac3" => an AC-3 Audio file
- ".amr" => an AMR Audio file
- ".dv" => a DV Video file
- ".m4e" => a MPEG-4 Video Elementary Stream file
- ".mkv" => a Matroska audio+video+(optional)subtitles file
- ".mp3" => a MPEG-1 or 2 Audio file
- ".mpg" => a MPEG-1 or 2 Program Stream (audio+video) file
- ".ts" => a MPEG Transport Stream file
- (a ".tsx" index file - if present - provides server 'trick play' support)
- ".wav" => a WAV Audio file
- ".webm" => a WebM audio(Vorbis)+video(VP8) file
- See http://www.live555.com/mediaServer/ for additional documentation.
- (We use port 8080 for optional RTSP-over-HTTP tunneling, or for HTTP live streaming (for indexed Transport Stream files only).)
通过VLC可以点播rtsp://192.168.1.41:8554/test.264视频,
(注意:test.264所在的目录要和live555MediaServer执行目录相一致,若test.264放在live目录下,则需要在live目录下执行./mediaServer/live555MediaServer)
4、交叉编译
编译器arm-hisiv100nptl-linux-g++
同理如果通过genMakefiles生成交叉编译的Makefile,我们需要一个对应的config.*
因此我们复制一个config.hi3518,命令:cp config.armlinux config.hi3518
- CROSS_COMPILE?= arm-hisiv100nptl-linux-
- COMPILE_OPTS = $(INCLUDES) -I. -O2 -DSOCKLEN_T=socklen_t -DNO_SSTREAM=1 -D_LARGEFILE_SOURCE=1 -D_FILE_OFFSET_BITS=64
- C = c
- C_COMPILER = $(CROSS_COMPILE)gcc
- C_FLAGS = $(COMPILE_OPTS)
- CPP = cpp
- CPLUSPLUS_COMPILER = $(CROSS_COMPILE)g++
- CPLUSPLUS_FLAGS = $(COMPILE_OPTS) -Wall -DBSD=1 -DLOCALE_NOT_USED
- OBJ = o
- LINK = $(CROSS_COMPILE)g++ -o
- LINK_OPTS =
- CONSOLE_LINK_OPTS = $(LINK_OPTS)
- LIBRARY_LINK = $(CROSS_COMPILE)ar cr
- LIBRARY_LINK_OPTS = $(LINK_OPTS)
- LIB_SUFFIX = a
- LIBS_FOR_CONSOLE_APPLICATION =
- LIBS_FOR_GUI_APPLICATION =
- EXE =
然后与在PC上编译一样,进行编译。
- root@kubuntu:/home/frank/live# ./genMakefiles hi3518
- root@kubuntu:/home/frank/live# make clean;make
这里要记得先make clean,否则因为之前在PC上编译的目标文件没清楚会导致链接失败。
编译时会产生一个错误
- In file included from MPEG4GenericRTPSink.cpp:22:
- include/Locale.hh:47:123: xlocale.h: No such file or directory
- In file included from MPEG4GenericRTPSink.cpp:22:
- include/Locale.hh:62: error: `locale_t' does not name a type
- make[1]: *** [MPEG4GenericRTPSink.o] Error 1
- make[1]: Leaving directory `/home/frank/live/liveMedia'
- make: *** [all] Error 2
这个是由于海思使用的是uClinux,并没有xlocale.h这个头文件,
而live555内部的一个locale模块调用了(见liveMeida/locale.hh),因此通过编译选项把他去掉。
修改config.hi3507,在编译选项上加入-DLOCALE_NOT_USED把此模块去掉。上面那段是已经去掉的
再次生成Makefile并编译
- root@kubuntu:/home/frank/live# ./genMakefiles hi3518
- root@kubuntu:/home/frank/live# make
编译成功!
5 移植到海思开发板上
将mediaServer的live555MediaServer(你可以试一下,在linux系统中打开这个是出错误的),通过nfs挂载到开发板上执行。运行后会出现
- LIVE555 Media Server-Test frank
- version 0.84 (LIVE555 Streaming Media library version 2014.10.07).
- Play streams from this server using the URL
- rtsp://0.0.0.0/<filename>
- where <filename> is a file present in the current directory.
- Each file's type is inferred from its name suffix:
- ".264" => a H.264 Video Elementary Stream file
- ".265" => a H.265 Video Elementary Stream file
- ".aac" => an AAC Audio (ADTS format) file
- ".ac3" => an AC-3 Audio file
- ".amr" => an AMR Audio file
- ".dv" => a DV Video file
- ".m4e" => a MPEG-4 Video Elementary Stream file
- ".mkv" => a Matroska audio+video+(optional)subtitles file
- ".mp3" => a MPEG-1 or 2 Audio file
- ".mpg" => a MPEG-1 or 2 Program Stream (audio+video) file
- ".ogg" or ".ogv" or ".opus" => an Ogg audio and/or video file
- ".ts" => a MPEG Transport Stream file
- (a ".tsx" index file - if present - provides server 'trick play)
- ".vob" => a VOB (MPEG-2 video with AC-3 audio) file
- ".wav" => a WAV Audio file
- ".webm" => a WebM audio(Vorbis)+video(VP8) file
- See http://www.live555.com/mediaServer/ for additional documentation.
- (We use port 80 for optional RTSP-over-HTTP tunneling, or for HT
测试的时候会发现RTSP的地址是0.0.0.0;
在nfs挂载的时候,已经用ifconfig eth0 192.168.0.166 将板子的IP地址设为了192.168.0.166 ,为什么还是0 呢
需要用到route add default gw 192.168.0.1,这个192.168.0.1是网关的IP地址,也就是你的路由器的IP地址,命令意思的是添加一条默认网关命令,将所有的数据包都转发到192.168.0.1;注意开发板上是运行./live555MediaServer,发现时没有端口号的,直接rtsp://192.168.0.166 就可以看到想要的结果,预祝成功。
